Porting of Exiode-Z

Post by Crazyboss » 25 Oct 2019 18:39

Hi.

As show at the Memofest 2019, the game Exiode-Z from the MSX, the port almost ran, there is a few bugs.

Now I started to port the game to ColecoVision which have the same Sound Processor, The interesting is now the game runs on those Emulators, it still have issues, but the Sound, is 100% equal to the Memotech (hardware) version, no one knows why the sound explosions sounds good on Memu.

I have tried it out on two ColecoVision emulators, with the same result.

More about this later :)

Ok now I tested ColecoVision code (it uses the same sound conversion routine as the Memotech Version).

All of them sound close to real hardware, the question is why Memu dont, Memu sound better than on original hardware.

I tested on:

Blue MSX (Colecovision)
CoolCV
MAME (Coleco ADAM Mode)

Just a thought but are you doing an IN (3) after OUT (6)?

Are you using OTIR or similar to update the sound?

Regards
THIS is what Memotech is doing now.
